Thank You, i'll prepare next version. Main question is: does this
approach(no SEQ_BEGIN, SEQ_END, 'msg_len' and 'msg_id') considered
good? In this case it will be easier to prepare final version, because
is smaller and more simple than previous logic. Also patch to spec
will be smaller.

Yes, it's definitely much better than before.

The only problem I see is that we add some overhead per fragment
(header). We could solve that with the mergeable buffers that Jiang is
considering for DGRAM.

If we are talking about receive, i think, i can reuse merge logic for

Yep, for TX the guest can potentially enqueue a big buffer.
Maybe it's still worth keeping a maximum size and fragmenting as we do 
now.

stream sockets, the only difference is that buffers are mergeable
until previous EOR(e.g. previous message) bit is found in rx queue.

I got a little lost.
Can you elaborate more?

Thanks,
Stefano
